The Virgo interferometer is a large-scale scientific instrument near Pisa, Italy, for detecting gravitational waves.The detector is a Michelson interferometer, which can detect the minuscule length variations in its two 3-km (1.9 mi) arms induced by the passage of gravitational waves.
Most of the current large interferometers started construction in the 1990s and finished in the early 2000s (1999 for LIGO, [5] 2003 for Virgo, [6] 2002 for GEO 600). After a few years of observation and improvements to reach their target sensitivity, it became clear that a detection was unlikely and that further upgrades were required, leading ...
The first direct observation of gravitational waves was made on 14 September 2015 and was announced by the LIGO and Virgo collaborations on 11 February 2016. [3] [4] [5] Previously, gravitational waves had been inferred only indirectly, via their effect on the timing of pulsars in binary star systems.
There are several ground-based laser interferometers which span several miles/kilometers, including: the two Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors in WA and LA, USA; Virgo, at the European Gravitational Observatory in Italy; GEO600 in Germany, and the Kamioka Gravitational Wave Detector (KAGRA) in Japan. While ...

Ground-based interferometers are now operational. [citation needed] Currently, the most sensitive ground-based laser interferometer is LIGO – the Laser Interferometer Gravitational Wave Observatory. LIGO is famous as the site of the first confirmed detections of gravitational waves in 2015
WASHINGTON ‒ Rep. Bennie Thompson, who led a House committee investigating the Jan. 6 riot, said there's been an "uptick" in threating calls against members of Congress since President Donald ...
